Students must be able to think at a high level in order to meet the requirements of the 21st century, including the ability to think critically. The mastery of student concepts about a material being studied influences the ability to think critically. The thing to remember is that all forms of critical thinking would not be possible without the main component of mastery of concepts. The purpose of this study is to describe the ability of critical thinking and mastery of the basic concepts of science among SMPN students in Central Lombok Regency. This type of research is a quantitative descriptive research with survey methods. Critical thinking tests and mastery of concepts by students using multiple choice instruments. The results showed that the average results: a) The critical thinking skills of nine high school students in Central Lombok were 71.69% with high criteria. The second critical thinking indicator, which provides further explanation, achieves the highest score in comparison with other indicators. b) Control of the basic concepts of natural sciences students with 76.20% with high criteria. The first indicator for controlling the concept is remembering who scores the highest score compared to other indicators

Critical thinking is a way of thinking by knowing and analyzing things to get a solution. Critical thinking skills applied in students to learn to solve problems / problems. This study aims to determine the ability of critical thinking of high school students in cooperative material in class X. The method used in this research is descriptive method. Subjects in this study are high school students of class X in Kabupaten Ciamis. The sample used is 93 students, consisting of 3 classes of 32 students from IIS 1, 27 students from IIS 2 and 34 students from IIS 3. The research instrument used is about knowledge about cooperative material which amounts to 25 choices double with four alternative answer choices, the questions used are arranged according to critical thinking indicator with C4-C6 cognitive level. Data analysis used is quantitative descriptive analysis. the average of students' critical thinking early ability is 49.35% (Low) or in the low category. The low initial ability of critical thinking makes the researcher assume that students are not used to get the problem with cognitive level of C4-C6 on cooperative material. So it is necessary to do better coaching to improve students' critical thinking skills. In addition, students are also required or accustomed in solving problems with high levels of cognitive C4-C6 or cognitive level.

PENILAIAN KETERAMPILAN BERPIKIR KRITIS DAN PENGUASAAN KONSEP PADA MATERI EKOSISTEMAbstractCritical thinking skills and mastery concepts are competencies that measure cognitive aspects. Both of these competencies support each other. This study aims to analyze critical thinking skills and mastery concepts of students in the ecosystem material. This was quantitative research. The sampling technique used Purposive Sampling, namely 60 high school students. Data was collected through the critical thinking skills test and mastery concept of ecosystem tests for students and interviews with the teacher. Based on the analyzed data, the average critical thinking skills and mastery concepts of an ecosystem are 53,15 and 61,10, which are in the low category. This is because students still have difficulty in understanding the basic concepts of ecosystems; students have not understood yet the terms in the ecosystem so that the terms with their meanings are often exchanged which has an impact on the low achievement of students.AbstrakKeterampilan berpikir kritis dan penguasaan konsep adalah kompetensi yang mengukur kemampuan kognitif. Kedua kompetensi tersebut saling berkaitan dan mendukung satu sama lain. Penelitian ini bertujuan untuk menganalisis keterampilan berpikir kritis dan penguasaan konsep peserta didik pada materi Ekosistem. Penelitian ini merupakan penelitian kuantitatif. Teknik pengambilan sampel yang digunakan adalah purposive sampling, yaitu 60 peserta didik SMA. Data diperoleh melalui tes tentang keterampilan berpikir kritis dan penguasaan konsep pada materi Ekosistem yang dikerjakan oleh peserta didik dan wawancara dengan guru. Berdasarkan analisis data, rata-rata keterampilan berpikir kritis dan penguasaan konsep materi Ekosistem peserta didik, masing-masing adalah 53,15 dan 61,10. Hasil tersebut termasuk dalam kaegori rendah. Hal ini disebabkan oleh sulitnya peserta didik dalam memahami konsep dasar Ekosistem, belum mengertinya istilah-istilah dalam ekosistem sehingga sering terjadi pertukaran istilah dengan maknanya yang berdampak pada rendahnya prestasi belajar siswa.

In 21st century learning, critical thinking skills are the main choice that must be mastered by students. This study aims to determine the effectiveness of local wisdom-based science teaching materials in improving junior high school students’ critical thinking skills. Most science teachers still apply teacher-centered learning, so students tend to be passive. This type of research is quasi-experimental with a pretest-posttest control group design. The study was conducted in the even semester of the 2019/2020 school year. The subjects of the research were grade VII students. Data collection techniques and instruments in the form of tests that include indicators of critical thinking skills. Data analysis used homogeneity test, Kolmogorov Smirnov normality test, independent sample t-test, and n-gain score. The results of the independent sample t-test are sig. (2-tailed) = 0,000<sig. α = 0.05. Students’ critical thinking skills in the experimental class were higher (N-gain score = 39.09%) than in the control class (N-gain score = 12.03%). Based on the study results, it can be concluded that there is a significant influence on the application of local wisdom-based teaching materials in improving the critical thinking skills of middle school students in the moderate category.

This article explores the skills and difficulties in critical thinking of junior Indonesian high school students in mathematics learning. Fifty students of grade IX who were purposive randomly selected from state junior secondary schools in Yogyakarta City were involved as the research subjects. The data were obtained from the test of mathematical critical thinking on the material of geometry. The test consisted of four items that describe each aspect of critical thinking skills, namely interpretation, analysis, evaluation, and inference. The analysis was done by showing the steps of the students ‘answers. The result indicated that the average of the aspects of mathematical critical thinking of students were on the high criteria with students’ greatest difficulties being in the analysis standard. Meanwhile,the average student success in the interpretation standard was 82%, the standard of the analysis was 46.25%, the evaluation standard was 78.25%, and the inference standard was 77%. Furthermore, from the results of the sample students’ exploration answers, it is expected that future teaching should not only focus on fluency in calculation but also on training the students in how to explain the solution steps of the problem solving process as this is important part in critical thinking.
